Where is the crankshaft position sensor located on an Audi Q5?

[BrodyLee]

The crankshaft position sensor on an Audi Q5 is typically installed inside the distributor. Function of the crankshaft position sensor: It detects the engine speed, hence also known as the speed sensor, and identifies the top dead center position of the pistons, thus referred to as the top dead center sensor. It includes detecting signals for controlling ignition timing for each cylinder's top dead center and the first cylinder's top dead center signal for sequential fuel injection control. Through the crankshaft position sensor, it can determine which cylinder's piston is at top dead center, while the camshaft position sensor identifies which cylinder's piston is in the compression stroke. Symptoms of a faulty crankshaft position sensor: During engine operation, if the crankshaft position sensor fails, it can lead to signal interruption, causing the engine to fail to start or immediately stall during operation. In such cases, the ECU can diagnose the fault and store the corresponding trouble code.
